To all wheel it may concern:

Be it known that l, PHILIP J. MARTIN, of Syracuse, in the county of Onondaga, in the State of New -i ork, have invented new and useful improvements inApparatus for W'eaving TuhularWire Fabrics, of which the following, taken in connection with the accompanying drawings, is a lull, clear, and exact description.

This invention relates to certain improvements in apparatus for the manufacture of Woven meta-l cable grips of the class' set forth in my Fatent No. 832,401, granted October 2, i906, whereby the same may be economically constructed by unskilled labor in such a manner as to produce in a grip made by it certain qualities which have been found to be of value therein.

The grip described in Patent No. 832,401 is known as a split grip. lt consists,likewise,

-. ol a plurality of strands of Wire or wire cord Woven into open mesh hollow body cylindrically shaped, but divided longitudinally, the strands not passing around the cylinder but being bent hack in the Weaving and forming eyelets at the divisional line. The strands have their middle portions twisted together to form two oiling tugs, one on each side of the cylincrically shaped hody, immediately alcove the Weaving, as practical tests have demonstrated the su eriority of tvvo loops over one in this sty e of grip. This grip, prone-rectory to use, is opened up and I placed around the caoleto be drawn at any desired point along the length thereof; lacing is passed through the above mentioned eyelots. The gripping action of these grips is due to the change of form of the meshes. When a pull is exerted on the pulling tug the meshes are elongated axially and narrowed circurolerentially; this'decrease's the diamstar of the gri and causes the same to firmly grasp the cab e. It is obviously of the greatest importance that this lessening of the diameter should occur simultaneously and uniformly throughout the entire length of the grip. To accomplish this, all of the meshes must at any one time be identical, or nearly so; and such identity can only be obtained by makin each crossin of the strands a joint, an by making a of the corresponding joints equidistanta art. Ow-

ing to the necessary stillness o the wire or Wire cord of which the grips are com posed, it has been found extremely difi'icult, if not altogether impossible, to obtain these results manually; and it is to overcome this difliculty and make possible the production of grip approximating perfection that my invention is intended.

This application, which is a division of my application Serial No. 369,557, filed March 4, 1907, has for its subject-matter, therefore, a cylindrical former having thereon a plurality of engaging parts adapted to receive the several strands of the grip, and to hold themat their points of intersection with means for clamping the strands at each point of intersection as it is finished. Sev eral forms of such apparatus are hereinafter set forth. I

ll y invention further consists in the construction, arrangement, and combination of parts hereinafter more fully described and claimed.

In the accompanying drawings, which form a part of this applicationzl igure 1 is a fiat development of a split grip Woven upon a formerconstructed accordance with this invention. Fig. 2 is an elevation of a former constructed in accordance With this invention, a cable being shown as being Woven thereon. Fig. 3 is a horizontal section through Fig. 2. Fig. 4 is a nerspective view illustrating the manner of forming articu- 8 lated joints hi the fabric. Fig. 5 is an elevation of another type of former. Fig. 6 is a horizontal section taken therethrough. Fig. l 7 is a perspective view of a part oi a completed grip.

One tye of the former is shown in Figs. 2 and 3. his consists essentially of a cylindrical body 15 of approximately the diameter of the grip to he made thereon, arising from a suitable base 1 6 and having in its surface a plurality of threaded holes, these holes being so disposed in the body that their locations are adjacent to the points of intersection of the strands of the grip to be woven thereon. Each of these threaded apertures is adapted to receive a headed screw or bolt l -l 1 1 2 2 2 2 etc. which is threaded to pair With thethread in the ap-- erture. As the 0 eration of this ty e of former is ractica ythe same-forbot the closed an split grips, whether ..withfone or being fastened thereon by a serving of cord --18- forming a completed tug. In the other .tug of this figure the servin is omitted, and

the individual wires of the undle are separated for' the purpose of permitting their course to be more readily traced, although they will be similarly served. The two gromets with their attached wires are now placed above the upper end of the former '-15- and the wires of the bundles opened out on both sides of the gromets and secured upon the periphery of the up er part of the former by means of a suitahle clip 19 shown in the figure as a wrapping, although it is obvious that a ring, either closed or open, could be employed for this purpose if desired or that any suitable form of fastening devices could be used. Having thus clamped the wires to the former at a point beneath the gromets the operator takes the wire-end h of one bundle. and lays it beneath the head of and close against the body of the stud 1 he.

then takes the corres onding wire-end -'H- from-the other bund e and passes it also beneath the stud and adj acent'thereto and over the wire-end h. Having drawn these wires tight he'clamps them in place by turning the headed bolt until its head bears on the two wire-ends, and. after they are so clamped he gives each wire-end a sharp bend by lifting the end of the wire-end h upwardly and away from the former and the other wire-end H toward the former. This is repeated at each intersection of two wire-ends and is shown in detail in the perspective view in Fig. 4. The wire end 9 1s now laid beneath the pin already been laid adjacentto that Bolt and their junction is clam ed by turning the bolt home and the desired is produced at the intersection by bending as before described; after which the wire-end G is lead beneath and adj acent the head of bolt 2 and is there ,crossedby the wire-end h, which has been already overlaid by the wire-end H at the bolt 1 and the intersection formed in the manner before described.

The process is repeatedwith the wireends f and e .of the one gromet and the ofwires,-the one'set of wire-ends E, 'F,

wire-ends F and E of the other giomet, these wire-ends c, f, gand h being each ends of the one bundle of wires; and E, F,

G and H beingends of the other bundle G, and'H-being laidin a and the ;other-s'et e", Lg, in..a le ft'-'hand twist.

right hand twist and 7:. being laid wire-end (Z whose .opposite'end' is laid with a left-hand twist tively,

' spiral 2 over the wire-end H-"which has is also spirally laid to the left, its first intersection the bolt 5, and the corres 'onding wireend D of the opposite bun e is laid in a right hand twist, its first intersection being with the wire-end h at the bolt 5". The wire ends a and A of the two tugs are brought around bolts 3 and 3'? respecand after being clamped they are carried ina left and right-hand spiral being with the wire-end H at res ectively and interlaced with the right an left hand wire-ends v reviously. laid. These wire-ends a and are given a slight right and left hand lay in leading them from the serving of the tugs so that they form at the bolts 3 and 3 loo s or bends 1 4 serving as points at whic the wra ping shown in'my said patent may be a p red. The wire-ends b and B' are li ewise given a right and left hand lay res ectivel and are interwoven 'atdpos'ts 4* an 4 wit the left and right han lays of the wire-ends a, and A,- respectively, before being brought around the bolts 5 and 5 after' which they themselves are given a left and right hand lay andinterwoven.-

with the previously laid wire-ends.

The wire-ends c and O'are given a right and left hand lay .res ectively and interwoven with the wire-en s a and b and A and B at 5 and 6" and 5 and 6 respectively, before being passed around the bolts 7 and 7 respectively, after which they themselves are given a left and right hand W en any wire end b itsectively. ay has been rought to bolts w ose exponent in the drawing is marked a and A, their lay is reversed and this is continued until by the method of weaving before delay res scribed a grip of the desired length has been formed.

It will be noted that by, the described lay the wire-ends of the bundlesare unequally distributed, that is to say that more of the ends of each bundle are laid in one lay than the other. Thus with the eight ends of each bundle shown by'Fig. 1 five of-such ends are given a right-hand lay as to one bundle and a left-hand lay as to theothei bundle, the remaining three wires of each bundle having a left and right hand lay respectively.

In order to provide for the increased number of intersections thus created in the middle rows of intersections and in the rows of' intersections on each side of such middle rows 'over the number of; loops 4 14 forming around the edge row of bolts whose exponents are marked a or A,

I. asshown prefer to start the first inter sections along vthe middle of the gri in a circumferential row of bolts above t e row or bolts which forms the first set oflacing loops -'14. By this means a perfectly even weave isT-obtained which is of great the pull exerted on the heads. J

In Fig. l I have designated the rows,

vertical and horizontal, in which the inter sections occur by numerals and letters. It

will be understood that a bolt will. be'

located at each such intersection and the foregoing reference character designated the bolts by the intersectin rows in which the are situated. It wil also be seen that ad itional vertical rows of intersections marked m and M are located between the rows 0 d and O, D, the first intersections on suc rows being at B Iand 6, being the crossing of wire-ends a and H' and A and h. It will further be seen that as shown in the fiat development seventeen vertical rows of bolts are shown, but in practice. the rows a and A may be the same as is the case in the showing of Fig. 3, in which event the grip is woven to the diameter of the former on which it is made.

After the grip has been woven in this man-- ner and completed the bolts are withdrawn and a perfectly smooth surface being given the former, it is slip ed therefrom.

It will be noted that by the abru t bend given to each wire beneath the hea s of the olts that a kink is formed therein which serves as an articulation upon which strands interwoven therewith turn.

Itis obvious that a closed tubular grip may be woven upbnthe former above described by properly laying the several strands and weaving them. In this case the ' the spiral lay of each wire is continuous from end to end and is not reversed upon itself as is necessary with the split grip, but the methodof producing the articulating joint is equally as ap licab e and the former serves the purpose as efore.

7 In Figs. 5 and 6 I have shown a modified type of former which is more expeditious in its use than the former previously described, in that it dispenses with the necessit 0f the individual manipulation of the b0 ts. In these figures the former consists of a tubular body 15" somewhat smaller than the diameter of the grip to be Woven thereon and havmg projecting therefrom a plurality of radial longitudinal ribs 20, in number equal to the number of longitudinal rows of intersections to be formed in the closed tubular gri to be woven thereon or to the numbero lon itudinal rows of intersections plus one to e formed with a split grip to be woven thereon. These ribs are detachable and are secured to the tubular body by means of screws 21, each rib being rovided with aseries of lugs 22 thereon ocated in the same relative arrangement as are the clamping bolts of the former shown in Figs. 2 and 3. The ribs do not extend all the way to the top within-t of the former, and the bundle or bundles of wire forming the loops around the pullin head gromets are secured on such u per en of theformer in the manner before escribed in connection with the former shown in Figs. 2 and 3.

A tubular sleeve '23 is adapted to fit over the former and the ribs thereon, being of such diameter as to be capable of rotating and sliding thereon over the lugs on the ribs. The lower end of this sleeve'is provided with a reentering portion .24 which may be formed by a step in the bottom thereof. In using this type of the former after the, wires have been gathered into bundles and looped around the gromets, with their wrap ings, and have been secured to the former y a tie, the wires are laid around the several lugs u on the ribs one at a time, and as each set 0 intersecting wires is thus laid and the intersections formed the sleeve which has been placed upon' the upper end of the former is, by either a rotary'or axial movement or both, so moved as to cause the shoulder upon the lower end thereof to cover and clamp that intersection, after which the wires are kinked as before described.

It will be generally found advisable to form the successive intersections circumferen tially around the former and thus the sleeve will be rotated, after making each intersection, through the distance between the two 'bs. After a horizontal row has been finished the first intersection of the succeedin row will be formed and. this will be covere by an axial movement of the sleeve. It will thus be seen that by the provision of this casing with an offset portion I am able to clamp each intersection as it is formed for the purpose of kinking and holding the Wires thereof and at the same time leave the adjacent strands at which the next succeed-.

ing intersection is to be made free from the manipulation of the wires thereon.

After the grip has been formed the sleeve is removed from the former, the screws holdin the ribs to the former removed, and the tu ular art of the former withdrawn from he grip. The ribs can now be collapsed or moved toward the axial line of the grip thus withdrawing the lugs thereon from engagement with the wires.

at I claim is:

In a former for weaving a wire fabric, the

combination with a tubu r bod of means for clamping wires thereto, an means for clamping the intersections of the wires as they are formed, substantially as described.

In witness whereof I have hereunto set my hand this 23d day of Se tember 1907.
